Specification of Letters Patent. Patented July 30, 1912.

Application filed ApriI 5, 1912. Serial No. 688,779.

To all fw/iom it may conce/m Be it known that I, BENJAMIN lVoL- HAUr'rEn, a citizen of the United States, residing at New Rochelle, in the county ot' lVestchester and State of New Yorl, have invented certain new and useful Improvements in Means for Insulating Rail-Joints,

`of which the following is a speeitication.

This invention relates to insulation for rail joints of the-insulated type, and more particularly to that character of rail-joint insulation known as divided-fiber wherein the insulation is in two parts, respec- 1; tively for the head and base flange portions 15,

; insulating material may be used to the best of the rails, whereby a minimum amount of advantage both electrically and mechanical-ly, and admitting of the ready removal and replacing of wornAout pieces of insulation withoutdisturbing or affecting the remaining good or unworn insulation.

The object of the presentinvention is to provide novel and practical means for et'- fecting a locking in plaeejot the'separatc pieees or sections of insulation in order to secure them against relative displacement or creeping under load conditions imposed thereon, thus contributing to the life of the insulation and n'iaintaining its proper insulating relation to the rails and to the joint bars. To this end, the 4present invention contemplates an improved means for interlockingl the separate pieces or sections ot' twofpait insulation for rail joints, primarily by an indirect interlock between the two atforded t 4^ ough novel combinations with the insulatin end post between the rail ends.

Tvvith'litliese and many other objects in View which willinore. readily appear as the details ,oi the invention are fully understood, the sameconsists in the novel construct-ion, combination, and arrangeme'i'it of parts hereinafter n'ore fully described, illustrated, and claimed.

j Though susceptible of embodiment invarioiis types of rail joints,.and adaptable for r .use with any 'form of joint bar or vsplice that flatet' d --lconstiuty ed and arrmigetl vin accordance with -may lie employed in an insulatedjrail joint, a fewy practica-l embodiments ot the inven- .jtion aresl'ilown 'for illustrative purposes in to Fig. l showing a modificationdoi:l the inl vention wherein dili'erent means' are einw ployed for locking both sections of insulation against longitudinal movement; the

view also illustrating the invention as eni.

ployed in connection with joint bars ot the 'continuous type,-. thereby illustrating the adaptability ot the,.improvements to various kinds of rail joints and joint bars. Fig. l is a vertical transverse sectional view at the lcenter of the oint shown in Fig; 3, the view 'illustrating the complete joint, and also illustrating the invention as employed in connection with the continuous type ol joint bar.

Lilie vreferences designate c n'iespondiiig parts in the several figures ot the drawings. The improved ii'isulation expedienls forniiiig the subject mattei' .ot' this application are intended to be' applicable to various kinds of rail joints, and hence available for use with fish plates, plain angle bars, angle bars of the continuous type, channel bars, or any of the divers forms of splices Avhich connect the rails and extend across the joint between them. In all of its apjilications the invention possesses the same utility and suby serves the same functions.

As above indicated, the present invention relates to novel means for interlocking the tivo sectionsv or pieces of divided-insulinion tor rail joints. usually in two yparts, respectively tor ythe head and base flange portions ot the rails. These separate sections are separately renewable `and replaceable, andby way ol illustrating the application of my invention thereto, reference is first made to fll`ig. 1 oit the drawings,'wherein is shown an insulated rail joint including the rails R, lt, side joint bars l, the usual joint bolts 2 having suitable bolt insulation 2, an insulating end post l between, the rail ends, and divided or twopart side iiisulation between the rails and the joint oars,said insulation comprising an upper head section 5, and a lower base seetion (S. '.llie insulation 3 is simply shown tor illustrative purposes and it will be unrl`his divided-insiilation is.y

same may' extend the ent-ire length of the joint or be otless extent, without affecting lthe ,improvements claimed Vherein.

plainly shown in Fig. l, the head seetionot insulation 5 is arranged above the line' of 115 joint bolts 2 and occupies an insulating position between the under sides/f the vrail heads and the bearing head of the adjoin-4 ing joint bar, while the lower or base sec-Y tion of insulation 6 is larranged over the base flange of the rails between 'the latter and the foot flange of the joint bar 1 said base section of insulation '6 also includineF at its inner edge an upstandi'ng` flange portion 7- arranged next to the webs of the rails to etlectually insulate the bottom inside corners of the joint bars from the rails.

A distinctive feature ot' the present invention resides in the provision of means for locking both sections of two-part insulation 'for rail joints, preferably through novel combinations with the insulating end post between the rail ends. Various ex! pedients may be utilized for accomplishing this result In illustration'thereot, reference is irst made to Fig. l of the drawings,

wherein the upper head section of insulation 5 is shown as being provided vwith a keeper socket or notch 8 which separably interloeks with a lateral locking tongue or 40 extension 9 projecting from the edge of the insulating end post 4, as is plainly shown in both Figs. l and 2 of the drawings. A direct interlock is thus secured between the insulating end post t and the upper or Ahead section of insulation 5, thereby efeetuallv v,preventing longitudinal movement, as well as downward displacement or movement of said head section o f insulation, while longitudinal movement of the lower orbase section of insulation 6 may bc accomplished by resorting to other means, such for instance as providing the flange port-ion 7 of each base section of insulation with bolt-receiving recesses or notches which bear' an interlocking,r relation to the joint bolts so that the latter act as stops to prevent said longitudinal movement of the base section. Accordingly, it will bey observed lhat in this form'ot' the invention it is the intentitni to prevent longitudinal movement of one ol the sections ot insulation by an interlock bev tween the same and the end post, and to prevent similar movement ot' the other seetion ol insulation by an interlock between G5 the saine :nul (he joint bolts, it being iun'uaf terial as far as the invention is concerned which section of insulation is locked by the joint bolts or which. is locked' by Athe end post.

Toillust-rate the intended vscope of the present invention, there is shown in Figs. 3 and 4 of the drawings a modification wherein the two sections of insulation 5 and 6 are locked together by means ofvk wide locking tongues or projections 1l, which are projected laterally from the-edges o-the web portion of the insulating end post 4 and are ot a sufficient length vertically to' extend entirely across the interval bet'ween the head and base sections of insulation 5 and 6 and to separably interlock with keeper sockets or notcheslQ and 13, which are provided in the inner edges respectively of the said head and base sections of insulation. It will thus be seen that according to this modification of the invention, both sections of the insulation have a direct, separable interlocking engagement with the locking elements of the end post, whereby -the latter eitectually secures both sections ot insulation against longitudinal movement. Furthermore, in Figs. 3 and t of thev draw-l ings, the adaptability of the improvements to' various kinds of joints and joint bars is exemplified by showing the same ernbodied in a rail joint including a joint bar la of the well ,known continuous type. To adapt the invention to the continuous type of joint bar, the base sect-ion of insulation is provided with a bottom piece or member .6 that is interposed between the bottom oit the rails and the Vrail supporting base plate ll of the joint bar.

Various other mod'iiications, and various changes in the form, proportion and minor 'details of construction may be resorted tol without departing from the spirit or sacrificing any .of the advantages of the invention. I
